Question

that可以在宾语从句中作从句的主语或宾语吗？what可以在定语从句中作从句的主语吗？

如果可以，请各自举一例，谢谢

Answer 1

that不可以在宾语从句中作从句的主语或宾语 that引导名词性从句时 只起连接作用 that不充当句子成分 本身也没有意思 句子完整意思完整时 名词性从句 就用 that 引导
如 it is well known that he works hard 主语从句
i think that the answer is wrong.宾语从句
the reason why he is often late is that he gets up late 表语从句
the fact that he is honest is well known 同位语从句
what不可以引导定语从句 可以写成 all that that引导定语从句
如 what you said is right 这是名词性从句作主语
= all that you said is right . all 是主语 that引导定语从句
也就是 what= all that

Answer 2

that不可以，只起连接作用
what 不可以作定语从句的关系代词。
一定不要搞混啊。
